WEATHER-STRIP.

Specification of Letters Patent.

Patented June 3th, M914.

Application filed March 2, 1914. Serial No. 822,006.

To all whom it may concern ie it known that I, J OIIN F. Poe, a citizenof the United States, residing at Oklahoma city, in the county ofOklahoma and State of Oklahoma, have invented certain new and usefulImprovements in Weather-Strips; and .I do declare the following to befull,

'clear, and exact description of the invention,

such as will enable others skilled in the art to which it apperta ii'isto make and use the same.

This invention relates to improvements in weather strips and moreparticularly to those which are primarily designed for use in connectionwith window sashes and frames.

The primary object of the invention is to provide adevice of thischaracter which will be simple in construction and efficient inoperation and which may readily be applied to any window sash and framewithout the necessity of making serious alterations therei n.

A secondary object is to construct one member of the strip in such amanner as to render it readily applicable to the groove in the windowframe in which the parting strip is usually employed.

Still another object is to construct the fixed and movable strips insuch a manner that escape of air between them will be practicallyimpossible.

lVith the above objects in view, the invention resides in certain novelfeatures of construction and combination herein described and claimedand shown in the drawings wherein Figure 1 is an inside elevation of aportion of a window frame and its upper and. lower sashes, showing theapplication of my invention; Fig. 2 is a horizontal section on the line2-2 of Fig. 1; Fig. 3 is a. vertical section on the line 33 of Fig. 2;and Fig. 4 is a detail vertical section on the line 4.4 of Fig. 3.

In the accompanying drawings, 1 have shown my invention as applied to awindow frame F which may be of any desired construction as long as it isprovided with grooves G for the reception of the parting strips whichseparate the upper and lower sashes U and L.

The stationary member of my improved weather strip is formed of a singlestrip of sheet metal having its opposite edges bent in such a manner asto provide substantially parallel. flanges 2 which are adapted toproject inwardly from the sides of the frame F when said member isforced into the groove G as clearly shown in Fig. 2.

Coat-ting with the fixed member, are movable members 3 which are alsoformed of single strips of sheet metal. l'iaving one of their edgessecured as at 4 to the sashes U or L while the remaining portions ofsaid strips are bent substantially upon themselves as at 5, said bentportions cont-acting with the inner side of the frame F, their remainingportions being then bent rather loosely around the 'free edges of theflanges 2 as shown at (3 and then extending inwardly inside of saidflanges, formed with inwardly extending beads 7 and having theirterminals 8 in contact with the inner sides of said flanges 2. Byreferring to Fig. :2, it will be seen that the only points ofcontactbetween the movable members 3 and the flanges 2 of the stationarymembers are at the bends 6.

and at the free terminals 8 of said members 3. By this construction andpositioning, the passage of air around the ends of the flanges 2 andpast the ends 8, is rendered practically impossible and yet allunnecessary friction is avoided. The beads 7 when the sashes are moved,run freely within grooves 9 formed in the opposite sides of a partingstrip 10 which is forced between said beads and the flanges 2 and isheld in position by said beads, no other fastening being necessary. Itmay be noted here also that by the construction and arrangement of thefixed and movable members, no fastening means are required for retainingsaid fixed members in position within the grooves G, the only points atwhich the improved strip is rigidly secured being at the points 4 wherescrews are preferably employed in order to render the various partsreadily removable.

The location of the various thicknesses of metal between the contiguousedges of the sashes U and L and the opposite sides of the groove G, inwhich the parting strip 10 was formerly secured, will necessitate movingsaid sashes away from said groove to a suitable extent. Thisnecessitates the moving of the remaining strips S which guide saidsashes in their movement and also causes considerable space to be leftbetween the lower rail R ofthe upper sash U and the upper rail r of thelower sash L. It therefore becomes expedient to provide a simple meansfor preventing the entrance of air rail 4-.

through this space and for this purpose, I

have provided a strip 11 of resilient metal which is secured to the railR by suitable fastening means 12 /along its upper edge while its lowerportion is bent in such a manner as to cause its extreme lower edge 13to contact with the continuous edge of the This means, though simple,effectually point.

In order that the ends of the rails R and 1 may move freely in respect.to the inner edges of the iarting strips 10, I preferably space saidchilsa proper distance from said strips. This necessitates the provisionof means for preventing the entrance ofair at this point, said meansbeing here shown in the form of fiat metal springs 14 which have theiropposite ends embedded in suitable notches formed in the parting strips10 and secured therein by screws 15 or other suit able fastening means.By reference to Fig. 2, it will be seen that the springs 14 are of thesame width as the parting strips 10 and that the ends of the'rails R and1" as well as the metal stri '11 contact with said springs, when the sases are closed, and thus effectually prevent the entrance of air. When itis necessary to raise the lower sash or lower the upper sash, theengagement between the ends of the rails R and r and the springs 14 willbe released upon a slight movement of said sashes whereupon they will befree to be raised upwardly or downwardly as the case may be.

I have before mentioned the fact that by the specific construction andpositioning of the fixed and movable parts of my improved weather strip,no fastening elements are necessary for the purpose of securing theU-shaped strip 1 and the parting strip 10 in position. Attention isagain directed to this fact since, in the manufacture of the device, itbecomes a very salient feature.

From the foregoing description, taken in prevents the .entrance of airat this connection with the accompanying drawing, the construction andoperation of the invention will be readily understood without requiringa more extended explanation.

Various changes in form, proportion and minor details may be resorted towithout de-- parting from the spirit of the invention as claimed.

Having thus described my invention, what I claim as new and desire tosecure by Letters-Patent is:

The combination with a window frame having upright grooves formed in itsside members and upper and lower sashes slidable on opposite sides ofsaid grooves, of a strip of-n1ctalU-shaped in cross section, in each ofsaid grooves and extending throughout the height of the frame, the freeedges of said strip projecting into the interior of the frame, and amovable member carried by each of said window sashes, said movablemembers being formed of single strips of sheet metal bent uponthemselves to one side of their longitudinal centers, their narrowerportions being secured to the contiguous sides of said sashes, and theirwider portions being bent substantially upon themselves around said freeedges of the U-shaped strip and formed into inwardly extending beads,the edges of said wider ortions being in yielding contact with the innersides. o the inwardly projecting portions of said U- shaped strips, andthe beads in said wider portions contacting with the inner edges of saidstrips, and a grooved parting strip within said U-shaped strips andretained threin by said beads.

In testimony whereof I have hereunto set -my hand in Presence of twosubscribing witnesses.
